AEROPLANE.

Speccaton of Letters Patent.

Patented Apr. 11, 1922.

' Application filed December 27, 1920. Serial No. 433,350. l

To all 'whom t may concern Be it known that I, RUDOLPH JARY, a citizenthe United States, and a resident of the city of Chicago, county ofCook, and State of Illinois, have invented certain new and usefulImprovements in Aeroplanes, of which the following is a specication.

My invention relates to aeroplanes, and it has 'for its principal objectthe provision of new and improved form and arrangement of parts by whichI shall be able to obtain increased carrying capacity, improvedstability, and easier and more complete control of the machine inoperation.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of partshereinafter described and claimed.

The invention will be best understood by reference to the accompanyingdrawing forming a part' of this specication, which drawing is aperspective view of myimproved construction.

In the drawing, 5 indicates a closed car of any approved type providedwith carrying wheels 6 revolubly mounted thereunder.

Transversely disposed above the car 5, I

have provided two superposed planes 7 and 8 which are mounted in spacedrelation with respect to each other and in spaced relation with respectto the car, being held in opera` tive position by any suitable means notillus` trated. In rear of the planes 7 and 8, I have provided twoadditional superposed planes 9 and 10 which are also mounted in spacedrelation to each other and in spaced relation with respect to the car7the upper and lower planes of the second pair being directly behind andin alignment with the upper and lower planes respectively of the firstnamed pair of planes. A fifth plane 11 is interposed between the upperplanes 7 and 9 ot the two pairs of planes, the plane 11 extend` ingtransversely at both sides beyondV the ends of the planes 7 and 9. Theseveral sup porting planes as above referred to are supported inoperative position with respect to each other by the use of any approvedmeans as is "fully understood in the art.

For carrying the machine forward, I have provided propellers 12 and 13mounted upon the horizontally disposed shafts 14 and 15 respectivelywhich are driven by the use of any suitable power means. I have alsoprovided a plurality of auxiliary propellers 16 mounted upon verticallydisposed shafts 17, such propellers 16 being mounted within verticallydisposed open cylinders 18 interposed within and extending between theupper and lower planes. By the use of the horizontally disposedpropellers 16, I am enabled to maintain the aeroplane in posi tion inthe air with avminimum of forward motion.r the propellers 16 beingdriven through the medium of the shaftsY 17 from any suitable source ofpower, either in unison with the propellers 12 and 13 or inde` pcndentlythereof.

At opposite sides of the car 5, I have provided supporting whee-ls 19upon the ends of the plane 3, such supporting wheels 19 being disposed ashort distance above the level of the supporting wheels 6. The aeroplanewhen in position upon the ground is designed to be supported by thewheels 6 of the car, the wheels 19 being provided merely as auxiliarywheels for use for a landing operation.

Gas bags 2O of any suitable type are secured at opposite sides of thecar below the planes 8 and 10, the gas bags being designed to maintainthe machine in position upon the surface of a body of water in case itis deemed desirable to land thereon.

F or maintaining the aeroplane in positionin the air and forassisting inguiding the motion of the machine during flight, I have provided animproved -form of means in rear of the supporting planes. This meanscomprises a horizontally disposed stabilizer plane 21 held in iXedposition with respect to the supporting planes by means of suitableiframe work extending rearwardly from the supporting planes. In theconstruction shown, the supporting` frame work or fuselage is in theform of a closed trame work comprising two arms 22 and 23. At the rearends of the arms 22 and 23, I have provided vertically disposed planesor rndders 24 which are pivotally mounted upon vertical axes withrespect to said arms. Cables 25 are provided leading to the forward partof the machine for controlling the position of the rudders 24. Ele`vator planes 26 are provided on opposite sides of the arms 22 and 237 asingle intermediate elevator plane being provided between the arms. Eachof the elevator planes 26 is pivotally mounted upon a horizontal axiswith respect to the stabilizer plane 21,

the position of the elevator planes being controlled by the use otcables 2T oi" any approved type extending from the elevator planes tothe 'forward portion ot the Inachine. Eelow the rear end portions ot`the arms 22 and 23 I have provided auxiliary carrying wheels 28 ot anyapproved type.

By the use ot my improved construction, a very great carrying capacityis provided, making the plane very desirable 'toruse commercially or foruse in warfare. By the provision of the horizontally disposedpropellers, the operator is enabled to hold the machine in substantiallystationary position in the air for photographing the position ol theenemy in warfare or tor enabling the operator to drop explosives at thedey sired point.

Wlhile I have illustrated and described the preferred form otconstruction tor carrying my invention into effect, this is capable otvariation and modication without depart ing trom the spirit ot theinvention. l, therefore, do not wish to be limited to the precisedetails oit' construction forth, but desire to avail myself ot suchvariations and moditications as come within the scope ot' the appendedclaims.

Having described my invention, what I claim as new and desire to secureby Letters Patent is :--V

l. An aeroplane comprising a pairot superposed planes, a second pair otsuperposed planes secured in rear ot said first named planes and uponthe same levelv therewith respectively, and a third plane bri( ingthegap between the upper two planes ot said pairs of planes andextending transversely at its ends beyond the ends of said Y planes andextending therebetween; a Vsecond propeller revolubly mounted on avertical. axis in said' cylinder; and means for rotating saidrsecondpropeller.

8 .-An aeroplane comprising aV pairof super-posed planes, a second pairot' super- ,posed planes secured in rear ot said irst named planes, athird plane bridging the gap between the upper two planes otpsaid twopairsot' planes and extending transversely `from one end to the otherotl said l. An aeroplane comprising a pair otl superposed planes, asecond pair ot superposed planes secured in rear ot'said lirst namedplanes, a third plane bridging the gap between the upper two planes otsaid two pairs ot planes and extending trans-V versely from one end tothe other of said planes, a closedv car for said aeroplane, carryingwheels revolubly mounted below said car, wheels on said planes atopposite sides ot the car above the level ot the wheels on said car, andfloat members secured onv said plane at opposite sides of the car 'forsupporting the machineV as a whole upon'tlie surface ot a body of water.

5. in airplane comprising a pair, of superposed planes; a second pairoit super posed planessocured in rear ot saidtirst named planes; a thirdplane bridging the gap between the upperptwo planes of said two pairs ofplanes and extending transversely trom one end to the other ot' saidplanes; a pair ol' rearwardly extending spaced supports mounted on saidplanes; a stabilizing plane connecting the'ends of said supports; andVvertical and horizontal rudders secured to said supports in. `rear ofsaid I stabilizing plane.

Vname to this'spe'citication in the presence of twosubscribingwitnesses.
